经典的GridView72种使用技巧(12)

}

public void bind() {

string sqlstr = \top 10 * from 飞狐工作室\ sqlcon = new SqlConnection(strCon);

SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open();

myda.Fill(myds, \飞狐工作室\ GridView1.DataSource = myds;

GridView1.DataKeyNames = new string[] { \身份证号码\}; GridView1.DataBind(); sqlcon.Close(); }

//这里就是解决方案

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e) {

switch (e.Row.RowType) {

case DataControlRowType.Header: //第一行表头

TableCellCollection tcHeader = e.Row.Cells; tcHeader.Clear();

tcHeader.Add(new TableHeaderCell());

tcHeader[0].Attributes.Add(\\跨Row tcHeader[0].Attributes.Add(\\ tcHeader[0].Text = \

tcHeader.Add(new TableHeaderCell());

//tcHeader[1].Attributes.Add(\\

tcHeader[1].Attributes.Add(\\跨Column tcHeader[1].Text = \全部信息\ //第二行表头

tcHeader.Add(new TableHeaderCell());

tcHeader[2].Attributes.Add(\\ tcHeader[2].Text = \身份证号码\ tcHeader.Add(new TableHeaderCell());

tcHeader[3].Attributes.Add(\\ tcHeader[3].Attributes.Add(\\ tcHeader[3].Text = \基本信息\ tcHeader.Add(new TableHeaderCell());

tcHeader[4].Attributes.Add(\\ tcHeader[4].Text = \福利\

tcHeader.Add(new TableHeaderCell());

tcHeader[5].Attributes.Add(\\ tcHeader[5].Attributes.Add(\\ tcHeader[5].Text = \联系方式\ //第三行表头

tcHeader.Add(new TableHeaderCell());

tcHeader[6].Attributes.Add(\\ tcHeader[6].Text = \身份证号码\ tcHeader.Add(new TableHeaderCell());

tcHeader[7].Attributes.Add(\\ tcHeader[7].Text = \姓名\

tcHeader.Add(new TableHeaderCell());

tcHeader[8].Attributes.Add(\\ tcHeader[8].Text = \出生日期\ tcHeader.Add(new TableHeaderCell());

tcHeader[9].Attributes.Add(\\ tcHeader[9].Text = \薪水\

tcHeader.Add(new TableHeaderCell());

tcHeader[10].Attributes.Add(\\ tcHeader[10].Text = \家庭住址\ tcHeader.Add(new TableHeaderCell());

tcHeader[11].Attributes.Add(\\ tcHeader[11].Text = \邮政编码\ break; } } } 前台：

16.GridView突出显示某一单元格（例如金额低于多少，分数不及格等）

效果图：

解决方案：主要是绑定后过滤 GridView1.DataBind();

for (int i = 0; i <= GridView1.Rows.Count - 1; i++) {

DataRowView mydrv = myds.Tables[\飞狐工作室\ string score = Convert.ToString(mydrv[\起薪\

if (Convert.ToDouble(score) < 34297.00)//大家这里根据具体情况设置可能ToInt32等等 {

GridView1.Rows[i].Cells[4].BackColor = System.Drawing.Color.Red; }

}

sqlcon.Close(); 全部后台代码：

using System; using System.Data;

using System.Configuration; using System.Web;

using System.Web.Security; using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient; using System.Drawing;

public partial class Default7 : System.Web.UI.Page {

SqlConnection sqlcon; SqlCommand sqlcom;

string strCon = \Source=(local);Database=北风贸易;Uid=sa;Pwd=sa\

protected void Page_Load(object sender, EventArgs e) {

if (!IsPostBack) {

bind(); } }

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) {

GridView1.EditIndex = e.NewEditIndex; bind(); }

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
